are usually provided with a: plurality of type wheels which maybe rotated either in i the same or in opposite directions"; It is therefore important that the rollsfor. inking the type be individual to each printing wheel independently rotatable;.and readily adjustable to various pressures depending upon the quantity of ink on..the .rolls.

The object of this invention is to provide rolls of this. character whichare somounted as to bereadily accessible for re-inking, located under the influence of individual springs so as atall times to remain in close contact with the type and at the sametime to be interchangeable andadjustable so; that the parts may be used for machines ot different type wheel arrangements.

Other objects of my inventionwillbeset forth in the following description-and-lthe appended claims.

My invention is illustrated inthe accompanying drawing in which Figure 1 isanvexteriorend view of theink roll case, illustrating its adjustments. .Fig. 2 is a section through the ink roll caseon the line 22 of Fig. 4. Fig. 3 is apartial section on the. line 3-3 of Fig. 2.. Fig. ,4: is an interior view ofthecase removed ,and Fig. 5 is an isometricsillustration of the details of the adjustable roller support.

In carrying out my invention the ink roll case 1 is preferably constructed of, cast metal and hinged at its loweriedge to thearnain inclosing case 2 of the printing machine by a pair of hinges 3, which are preferably arranged: so that the ink roll. case-may be read-.

ily removed by sliding it longitudinally. Pivotally attached to each end of the case 2 are slotted adjusting latches 4, so engaged by the pins 5 that the shank of thumb screws 6 will enter the openings 7 as the case 1 is swung upward about its hinges 3. By'means of the thumb screws 6 the case 1 maybe eheld in any positionto give thehdesiredpres .SHI'QtbQtWQQil the Uink'Srolls. and the revoluble type wheels.

In order that the samecase and parts may be used with printingimachines .havingidif- ,ferentgarrangements of. typewheels the T shaped'supporting members-8 are made ad- :justable to any position within the case 1. To accompllsh this, a rod 9 issupportedin e'ach end'ofr thecase 1 and passes through openings inone end of each of the Tshaped 5 supports 8. l IThese supports. are veach pro- \vided iwith aipai-rof. adjusting screws 10 which act to maintain the supports in'proper longitudinal position 1 and "also act in conjunction with the rod 9 to maintain thesupport 8 inproper alinement, thus avoiding pthe. necessity of machining the inside of the I :wrollere supporting. case. r. Each support is providedkwith a cylindricalslotted aperture 11 ,iorming a seat for spring 12 and forming a guidelfor, the plunger 13 which presses :against oneend of: one of the. shafts 14 about which thelink rolls '15 rotate, each spring qthusacting. individually on itsendof one ofthe shafts ltoimaintain one of the ink {rolls incontactiwithits type wheel ata pressure determined by. .theadjusted position of rtheacase 1.

In. order to holdtheashafts 14. in place i ,when... the rolls are out of contact with the type wheels the spring plates '16 are provided, thesebeingsecured to the faces of the T shaped supports -by..means of screws 17 andrprevented from. turning by the embossing 18 engaging a depression: in the support. The extended endsof the spring plates 16 ,press against theheads of the screws 10 and thulsfiprevent them frombecoming loosened .throughz-the 3' ar incident. tothe operation of .7 the printing machine.

1 \Itthas been found, practice that the ink rollstand typeshould notbe maintained un- ,deri-pressure-contactwith oneanother for an eXtended .period when the printing machine I is notinuse. -The,slotted latch 41: provides means for relieving the pressure or even en- ,tirel-y removlng the contactbetween the ink ,rolls and the type wheels on such occasions.

While I have shown and described my invention in a particular form it is to be understood that I do not wish to be unduly limited thereto, many modifications being possible without departing from the spirit or scope of my invention.

I claim 1. In combination with a pluralityof 1ndependently rotatable type wheels, an ink roll for each wheel, an independent spring for each'roll, and a case adjustable with respect to said typewheels in which said inkvv rolls'are reciprocatively supported. a

, 2. In combination with a plurality of independently rotatable type wheels, an ink roll for each wheel, a case or housing for said'ink rolls, andink roll supports yieldingly carrying said ink rolls adjustably secured within said case whereby the same housing and supports may be used for various lengths of ink rolls.

3. In combination with ,roll for each wheel, a hinged casefor said rolls, shafts upon (which said 1 rolls are mounted, adjustable supports for said shafts,

aspring within eachsupport, each acting 1 upon one end ofrrone of said shafts'and means-to adjustthe position of saidcase to regulate the pressure of'said springs upon said shafts andof the rolls upon said type wheels- V V 4. In. combination with a check printing 7 machine, an ink r011 carrying case hinged to the frame of the machine, ink rolls yieldingly carried in said case, type wheels in the 1, machine but outside said case, a slotted latch pivoted to the frame, a thumb screw carried by thecase engaging said latchand extendsaid typewheels and caused to engage there- 1 ingthrough the slot'therein for holding the case in various positions whereby the ink rolls may be moved toward or away from f, with with varying pressures.

5. In an inking device for printing machines thecombination with a casing, of a j plurality of ink; roll 7 supports mounted within said casing, means for securing the supports at any position alongthe casing, ink roll shafts extending between said sup- '4 5 ports and yieldingly supportedtherein, and

' ink rollsjournaled on said shafts.

I 6. In an inking device for printing maschines, the combination w1th an ink roll ini closlng case, of 111k roll supports, means associated with said inclosing case for retain- 7 ing the ink roll supports therein but permitting said supports to be moved to any position throughout the length of said case, and

means associated with each individual support for securing the same 1n any desired 7 position in the case, andink rolls yieldingly Copies 91' this patent may be obtained for v I l 7 r i j Washington, D. 0.

g a plurality of in-' 'tlependently'rotatable type wheels, an ink mounted between said supports, the adjustability of said supports permitting ink rolls of varying lengths to be mounted in any de sired position in the ink roll frame.

7 Incombination with a rotatable type wheel, of an ink roll, a hinged case for said.

casing and adapted by their adjustment to change the relative alinement of the support. 9. In an inking device, the combination with an ink roll casing, of ink roll supports in said-casing, screws passing through each support and engaging opposite walls of the casing and adapted by their. adjustment to changexthe relative alinement of thesupport and a" spring plate secured to each support and engaging the heads of its adjusting screws to prevent them from loosening.

10; In an inking device, the combination with an ink roll casing, of ink roll supports in said casing, a screw passing through the support and engaging the inner wall of the casing to hold its support in position and a spring plate secured to the support and engaging the head of said screwto prevent it from loosening. v

11. In an inking device, the combination with an ink roll casing, of slotted inklr'oll supports in'said casing, an ink roll shaft reciprocatively mounted in slots of two of said supports, a screw passing through the support and engaging an inner wall of the casing 'to hold its support in position and a spring plate removably secured to each support for retaining the ink roll shaft in the slot in the support, said'plate also engaging the head of said screw to prevent thelatter from loosening.
